ColorFull::Tree_level_gluon_basis Class Reference
Inheritance diagram for ColorFull::Tree_level_gluon_basis:
Detailed DescriptionThis class is for containing tree level gluon bases, i.e. bases of form Tr(t^a t^b....t^z) +/- Tr(t^z .... t^b t^a), where the sign is given by (-1)^n_g. Technically only one of the quark-lines are carried around in the cb member, the other is implicit. This speeds up calculations. Constructor & Destructor Documentation◆ Tree_level_gluon_basis() [1/2]
Default constructor. ◆ Tree_level_gluon_basis() [2/2]
Constructor for creating a tree level gluon basis with n_g gluons. Member Function Documentation◆ create_basis()
Creates a basis with basis vectors saved in the cb member. Each basis vector is a sum of two traces, of form Tr(t^a t^b....t^z) +/- Tr(t^z .... t^b t^a). The charge conjugated trace is implicit, and only one trace is actually carried around. ◆ read_in_Col_basis() [1/2]
Function for reading in the basis from a file. The file should contain the whole basis, including the charge conjugated part. Reimplemented from ColorFull::Col_basis. ◆ read_in_Col_basis() [2/2]
Function reading in the basis from default name (see basis_file_name in the Col_basis class). The full basis, including the charge conjugated part should be contained in the file. (This is to simplify comparison with other programs, such as ColorMath.) Reimplemented from ColorFull::Col_basis. ◆ write_out_Col_basis() [1/2]
Function for writing out the basis to default name, (see basis_file_name in the Col_basis class). The full basis, including the charge conjugated part is written out. (This is to simplify comparison with other programs, such as ColorMath.) Reimplemented from ColorFull::Col_basis. ◆ write_out_Col_basis() [2/2]
Function for writing out the basis to filename, (see basis_file_name in the Col_basis class). The full basis, including the charge conjugated part is written out. (This is to simplify comparison with other programs, such as ColorMath.) Reimplemented from ColorFull::Col_basis. ◆ write_out_Col_basis_to_stream()
Function for writing out the basis in a human readable format to an ostream. Reimplemented from ColorFull::Col_basis. The documentation for this class was generated from the following file:
